Any one running oil breathers?

Anyone running oil breathers?

**Newbie Question**

I wanted to remove my pcv valve on the drivers side of my 99 hoe and install a oil breather. Is this anygood to do and has anyone installed one?

Thanks

You should not remove the PCV for any reason. If you have enough "blow by" that it does not keep up, you can add breathers. The PCV will keep the crank case fumes at a minimum while the engine is at an idle.

Forced induction engines often have positive crank case perssure while under boost. That is when you either need a vacuum pump or additional breathers.

If you are normally aspirated and are having blow by problems, it's time to rebuild the engine.

"Blow By" meaning oil in the intake?

There is always a certain amount of air/vapor, that gets past the rings, from combustion.

It is directly proportionate to the combustion chamber pressures and the wear factor of the rings and cylinder walls.

In a normally aspirated engine in good condition, the vapors are normally handled by the PCV system. When “blow-by” exceeds the capability of the PCV system, those vapors come out somewhere. If there is no breather, the crankcase pressure rises and generally shows itself by creating oil leaks around the valve covers or timing cover, or intake manifold.

Many drag racing engines have vacuum pumps to deal with blow-by. In the case of a forced induction engine running on the street, a breather or two, is more than enough for the occasional need to expel blow-by.

That’s the short answer I guess……..
